Water lost through transpiration is

Options

A. Pure water
B. Rich in organic solutes
C. Rich in dissolved salts
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Transpiration:**
- Transpiration is the process by which water evaporates from the aerial parts of plants, primarily through small openings in the leaves called stomata.

2. **Nature of Water Lost:**
- During transpiration, water molecules are released into the atmosphere. This process primarily involves the evaporation of water.

3. **Composition of Transpired Water:**
- The key point to note is that when water evaporates, it does not carry with it the dissolved substances (like salts and organic solutes) that may be present in the plant's sap. Only the water molecules evaporate.

4. **Conclusion:**
- Therefore, the water lost through transpiration is pure water, as it does not contain any dissolved salts or organic solutes.

**Final Answer:**
- Water lost through transpiration is **pure water**.
